Abstract
The utility model relates to a tool for manufacturing a heat preservation box of a nuclear power station, in particular to a pair of pliers with saw teeth, and solves the problems that a operation for manufacturing a sawtoothed belt is complex when existing tinsmith snips is used, and the shearing effect is pour. The pair of pliers with the saw teeth comprises a plier blade, a plier blade groove, an inserting-opening handle and a bell-mouth handle. A blade body of the plier blade is in a triangular-prism-shaped structure with an outward top angle and is connected with the inserting-opening handle through a transmitting stud shaft. A blade body groove of the plier blade groove is a triangular groove matched with the structure of the blade body and is connected with the bell-mouth handle through a transmitting stud shaft. The plier blade and the plier blade groove are connected through a driven stud shaft, the inserting-opening handle and the bell-mouth handle are connected through a driving stud shaft, and the blade body is driven by the inserting-opening handle to rotate in the blade body groove with the driven stud shaft as a pivot. When the pliers with the saw teeth is used to manufacture the sawtoothed belt, with only once shear, at least one triangular tooth groove is sheared out on the edge of a iron sheet, shear efficiency is high, shear effect is good, the strength of the saw teeth is high. The tooth grooves are the same and distributed evenly, and the manufactured sawtoothed belt is attractive and high in strength.
Description
Technical field
The utility model relates to the instrument that is used for preparing incubation chamber in the Nuclear Power Station, relates in particular to a kind of serrated pliers that is used for making incubation chamber cambered surface and plane binding site usefulness saw tooth belt.
Background technology
When make building the Double wall insulation box of used in nuclear power station, as shown in Figure 1, need to use sawtooth with the binding site on plane 02 be that leg-of-mutton saw tooth belt 03 is connected to cambered surface 01 on the incubation chamber.At present, prepare this saw tooth belt and normally cut suitable sawtooth with tinsmith snips along the iron sheet edge.But tinsmith snips whenever cut a triangle sawtooth needs to cut two cuttves, complicated operation at least; When shearing, when wiping out a triangle iron sheet piece of iron sheet edge, two limits of shearing out very easily are positioned at the tooth root that place, summit, teeth groove place intersects and clips to its adjacent sawtooth at this triangle iron sheet piece, so that the connecting portion of sawtooth and iron sheet narrows down, even so that sawtooth cut by whole, affect the intensity of saw tooth belt, and then affect the intensity of incubation chamber; The leg-of-mutton shape and the size that only rely on workmen's range estimation or feel to determine to wipe out, the sawtooth of the saw tooth belt that completes is not of uniform size, shape is different and skewness, both affect the intensity of incubation chamber, affected again the attractive in appearance of incubation chamber cambered surface and plane binding site.
The utility model content
Make the saw tooth belt complicated operation for solving with existing tinsmith snips, and the poor problem of shear effect, the utility model proposes a kind of serrated pliers, this serrated pliers comprises pincers cutter, pincers cutter groove, socket handle and bellmouth handle; The cutter hub of described pincers cutter is the outside triangular prism shape structure of drift angle, and is connected with described socket handle by transmitting stud shaft; The vee gutter of the cutter hub groove of described pincers cutter groove for being complementary with the structure of described cutter hub, and be connected with described bellmouth handle by transmitting stud shaft; Described pincers cutter is connected by driven stud shaft with described pincers cutter groove, described socket handle be connected the bellmouth handle and connect by stud shaft initiatively, described cutter hub is being rotated in described cutter hub groove take described driven stud shaft as pivot under the drive of described socket handle.
When adopting this serrated pliers to make saw tooth belt, shear and once can cut out at least one triangle teeth groove in the iron sheet edge scissor, and can not have influence on the tooth root of the sawtooth adjacent with teeth groove, shear efficiency is high and shear effect good, and sawtooth intensity is high; The triangle teeth groove of at every turn shearing out is identical and be evenly distributed, and the saw tooth belt of making is attractive in appearance and intensity is high.
Preferably, sheathed torque spring on described active stud shaft.Like this, after shearing was finished, handle was strutted by torque spring, and then cutter hub and cutter hub trench brace are opened, and shear convenient next time, improved shear efficiency, reduced production cost.
Preferably, be provided with the protection projection at a handle of this serrated pliers, this protection projection is positioned on the position of described handle middle part deflection handle tail end and towards another handle.Like this, when shearing, the handle that can avoid operating personnel's finger to be closed crushes, and has improved the security performance of serrated pliers.
Preferably, be provided with in the bottom surface of the cutter hub of described triangular prism shape structure two extend from drift angle along dual-side and blade towards the cutting knife of cutter hub groove.
